2 Claims.

This invention relates to hooks, and primarily to hooks used as bullsnaps or in connection with harness, halters or the like.

The primary object of the invention is to provide a hook of thischaracter which, when moved to its closed or active position, will besecurely held in its holding position, against accidental displacement.

An important object of the invention is to provide a hook of thischaracter which is held in its holding position by a wedging action setup between a pair of cooperating hook members, the hook being entirelyfree of spring devices which are perishable, and break readily,rendering the hook inoperative to accomplish its purpose.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein described, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings:

Figure l is a side elevational view of a hook constructed in accordancewith the invention, showing the hook in its closed or holding position.

Figure 2 is a view illustrating the hook in its open position.

Figure 3 is an elevational view illustrating one edge of the hook in itsclosed or holding position.

Figure 4 is an elevational view of one edge of the hook, illustratingthe hook members as in their open positions.

Figure 5 is a vertical sectional view on line 5-5 of Figure 1.

Figure 6 is a side elevational view of a modified form of hook.

Figure '7 is a sectional view taken on line 1-1 of Figure 6.

Figure 8 is an enlarged fragmental sectional view illustrating the wedgelocking means.

Figure 9 is an enlarged sectional view taken on line 9-9 of Figure 10,and illustrating a further modified form of the invention.

Figure 10 is an elevational view of one of the side faces of the lockingwedge.

Figure 11 is a sectional view taken on line llll of Figure 9.

Referring to the drawings in detail, the hook comprises a body portionincluding hook members 5 and 6 which are pivotally connected by means ofthe pivot pin 1' which extends through the upper ends of the hookmembers.

The reference character 1 designates a pin extending inwardly from theinner face of the hook member 5, the pin being provided to extend intothe opening 8 of the opposed hook member 6. A pin indicated at 9 is alsoformed on the hook member 5 and is adapted to be positioned in theopening 10 of the hook member 6. A pin indicated at H extends inwardlyfrom the hook member 6 and is adapted to extend into the opening l2 ofthe hook member 5, when the hook members are moved to their closed orgripping position.

As clearly shown by Figure 5 of the drawings, the inner surfaces of thehook members 5 and 6 are beveled at their upper ends, and receive thelocking disk I3, which is also pivotally mounted on the pivot pin 6.This locking disk I? is also beveled, so that the wide portion thereofwill move-between the hook members 5 and 6, to move the hook memberswith respect to each other. It will be obvious that when the lockingdisk I3 is moved to the position as shown by Figure 5 of the drawings,the hook members will be locked in their closed positions, and can onlybe moved to their open positions, by rotating the locking disk to theposition as shown by Figure 4. An enlargement [4 is provided on thelocking disk l3 and is adapted to seat in the recess l5 of the hookmember 6, holding the locking disk against accidental movement, whilethe hook is in use. In order that the locking disk may be readilyrotated, the periphery thereof is knurled as at [6.

The reference character I! designates a yoke, which is also pivotallyconnected with the body portion of the hook, the yoke being providedwith a ring I8, which is swiveled thereto, to permit the hook to berotated with respect to its supporting chain.

In the modified form of the invention as shown by Figure 6 of thedrawings, the adjacent side faces of the hook members 20 and 2 l' arebeveled, so that when the hook members are moved to their holdingpositions, or the positions as shown by Figure 6 of the drawings, thehook members will be wedged into close engagement with each other.

Formed on the outer edge of each hook member, is a flange indicated at22, and these flanges are adapted to engage the edges of the adjacenthook member restricting movement of one hook member with respect to theother, in opposite directions.

As shown by Figure 8 of the drawings, the

wedge-shaped member which is indicated by the reference character 23,and which moves between the upper ends of the hooks, is provided with abore in which the spring-pressed pin 24 is mounted, the spring-pressedpin adding a rounded end to fit within the recess 25 formed in one ofthe hook members.

In the form of the invention as shown by Figure 9 of the drawings, thelocking disk 26 is provided with a curved groove 28 in which the springmember 27 is held, one end of the spring member 21 extending outwardlyso that it bears against the adjacent surface of one of the hookmembers, the hook member with which the spring engages, being formedwith a recess 36 into which the spring member will move, when the hookmembers are moved to their holding or closed positions.

It will of course be understood that a slight pressure to rotate thelocking disk, will result in the spring member becoming disengaged withthe walls of the recess, to permit the free rotary movement of thelocking disk.

The spring member 2? has its free extremity extended rearwardly as at 23providing an inclined surface so that the spring member will ride out ofthe recess 30 when it is desired to rotate the locking disk 26.

From the foregoing it will be seen that due to the construction shownand described, I have provided a springless hook which may be used inconnection with harness, or in any other place where a hook isdesirable, the hook being of a construction to be securely held to thearticle with which it is connected, against accidental displacementwhile in use.

What is claimed is:

l. A hook of the class described, comprising a yoke, a pair of hookmembers pivotally mounted within the yoke, the adjacent inner surfacesof the hook members at the inner ends thereof being beveled, a beveledlocking disk mounted between the beveled surfaces of the hook members,said locking disk adapted to move said hook members into engagement witheach other as the locking disk is rotated in one direction, and meansfor restricting pivotal movement of the hook members with respect toeach other.

2. A hook of the class described comprising a yoke, a pair of hookspivotally mounted within the yoke, the adjacent inner surfaces of thehook members being beveled, a beveled disk mounted for rotary movementbetween the hook members, pins extending from the inner surface of oneof the hook members, the opposite hook member be- .ing formed withopenings to receive said pins holding the hook members against pivotalmovement with respect to each other, said disk having an enlargement,and one of said hook members having an opening to receive theenlargement, holding said disk normally against rotary movement.
